WINDOW.

Application filed March 25, 1915.

T all whom t may concern:

Be it known that I, THOMAS H. KANE, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful lVindow, of which the following is a specification.

This invention relates to a window including mutually counterbalancing sashes, an one of its objects is to provide a construction wherein considerable ventilation may be obtained at the meeting rails without creating a draft at the sill level. For this purpose a pair of connected sashes are employed, one of which has a combined sliding and swinging movement, the other being arranged to slide in a vertical plane. Other objects of the invention are to provide means for s0 controlling the movement of the rst mentioned sash that it is caused to assume a position parallel to the other sash after being moved a predetermined distance; to provide means for sealing the joint between the sash that has the combined movement and the frame; to provide means for conveniently securing the sealing means in position; to provide a tight joint between the meeting rails of the' sashes; to provide a device in which the usual screens and awnings may be used; and to improve the construction of the window generally.

The nature of the invention will be Amore fully understood from the description and drawings, wherein one embodiment of my invention is shown, and in the latter of which Figure 1 is a vertical section of the window. Fig. 2 is a fragmentary view from theinside, parts being broken away. Fig 3 is a diagrammatic section on the line 3-3 of showing the window partly open. 4 is a similar section, the window being entirely open. Fig. 5 is a horizontal section through the lower sash and adjacent parts.

Similar reference characters refer to like elements throughoutv the several views.

the outside of the win- For convenience, dow or building will be termed the forward side and the inside, the rear, while those portions of the frame that project into ly. In the embodiment of my invention shown, the main side members are formed of rolled I-sections 1 having flanges 2 inclined ininward wardly toward the central plane of the win- Speccation of Letters Patent.

dow.. The upper ends of the main members are joined by the top plate 8 comprising an edge flange 4 and an intermediate flangev 5, the latter being shouldered at 6; and a sill plate, similar in cross-section and reversely arranged, connects their lower ends. These elements are disclosed in my United States application for patent filed January 8th, 1915, Serial Number 1087; and, while desirable in the present construction, may be replaced by sections of other forms. The upper rail 8 and side bars 9 of the upper sash, together with the guide strips 10 therefor, and the wedge strips by which the guides are thrust sidewise and clamped in position, may be of the same cross-section as those shown in the above mentioned application, or other desired members may be used in their stead.

It will be noted that the wedge strip comprises a forward flange 12 and a rear flange 13 that are joined to a body portion 14 by inclined shoulders 15, and that the whole strip is adjustable toward the sash by screws 16. If desired, the rear flange may be removed from a point at about the level of the meeting rails upwardly, as shown in Fig. 1; and the extreme upper ends of both wedge and guide strips may be cut away at 18 to allow the attachment of a bracket 19, upon which a counterbalance pulley 2O is carried, directly to the main side member 1. i

Supported upon the rear portion of the side members in each instance is a combined guide and sealing member, substantially U- shaped in cross-section, one flange 22 preferably being beveled on its rear edge and having a beveled rib Q3 along its forward edge, whereby the whole member may be wedged into and retained in position against the flange 2 by simply adjusting the screws 16. The saine action, it will also be observed, secures the guide strip 10 for the forward sash in place (Fig. 5). The other flange Q5 of the guide and embraced by the U-shaped side bar 26 of the lower sash, whereby a tight joint is formed when the window is closed; and, for the same purpose, the upper rail 27 of the lower sash is provided with the vertical flange 28 (Fig. 1) that terminates in a horizontal flange 29, and with a second horizontal flange 30 spaced a distance from the flange 29 substantially equal to the thickness of a rearsealing member is lower rail 32 of the upper sash. As shown,

' the flange 30 is one leg of an angle Iiron 33 riveted to the vertical flange 28.

The lower rail of the lower sash has on each side a bracket 35, from each of which projects horizontally a pin 36 carryingv a roller 38 that bears upon the front face of the corresponding combined guide and sealing member. Secured to each of the bars of the lower sash at a point considerably A.below the upper rail is a pivot 4:0 to which-is attached a link 4l, the other end of the latter being capable of swinging about a second pivot 42 fixed to the side member of the frame. lhe sashes are connected for supporting and Llcounterbalancing purposes by a tapeorchaineg, one end la of which is secured in any desired manner to the upper sash, the other end being continued downwardly'alongvthe side member of the lower sakshto ya point in proximity to the sill and there secured to a pin or other part 45 rigid with the sash. s

Operation.

The` arts normally occupy the osition indicfatdd in Fig. l. When it is d eired t0 secure ventilation, the lower sash is swung rearwardly on the pivots or pins 36 until the flanges 29-30 clear the flange 31 on the uppersash, afterwhich the sashes may be shiftedveasily to form a slight opening at bottom and top. A much greater opening 1s rails, for the link 4l forces the upper part of the lower sash rapidly rearward. Further elevation of the lower sash will cause it to swing inwardly about the pins 36 into parallel relation tofthe upper sash, as'indicated in Fig. 4. The joints 25-26 at the sides` of the swinging sash and the joint 29-30-31 at the vmeeting rail effectually eX-` clude air. and moisture.

Because of the fact that the lower sash swings rearwardly, it is possible to employ the usual screens andV awnings. VIt will be seen that the sections from which the window is made are of shapes that m'ay readily be rolled,which is of'importance, since the cost is reduced thereby, and also because it admits the use of heavier and stronger parts than can be obtained by pressing or stamp/ing. Y Itis clear that many Achanges may be made ill detelsof construction vwithout, departingI from the spirit of my invention. For example, the "combined gnide and seal- 111g 111.6111581'. may be of H-cross-section instead of U-shape, as shown. "I do fore,lwi'sh to be limited.: otherwise than as indicated 'by the subjoined claims.
